One Merge to Rule Them All: From Galaxy Interactions to Black Hole Mergers Using Horizon-AGN

Ecaterina Leonova, Marta Volonteri, Clotilde Laigle +3

Galaxy mergers are fundamental drivers of galaxy evolution and black hole (BH) growth across cosmic time. We use the Horizon-AGN simulation to investigate the fraction of galaxy pa…

The LISA Astrophysics MBHcatalogues Project: A comparison of predictions of simulated massive black hole binaries

David Izquierdo-Villalba, Melanie Habouzit, Matteo Bonetti +67

In the hierarchical paradigm of galaxy formation, central massive black holes (MBHs) are expected to coalesce after the merger of their host galaxies. One of the main goals of the…

PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy

Himanish Ganjoo, Yann Rasera, Emilio Bellini +18

Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…

Cosmic reflections I: the structural diversity of simulated and observed low-mass galaxy analogues

G. Martin, A. E. Watkins, Y. Dubois +10

Dwarf galaxies serve as powerful laboratories for investigating the underlying physics of galaxy evolution including the impact of baryonic feedback processes and environmental inf…

Dissecting the formation of gas-versus-star counter-rotating galaxies from the NewHorizon simulation

S. Peirani, Y. Suto, S. Han +5

(Reduced)Using the NewHorizon simulation, we have studied ten gas-versus-star counter-rotating galaxies in field environments with a stellar mass of M*~[1-5]x10^10 Msun. For all of…

Signatures of simulated spiral arms on radial actions

P. A. Palicio, A. Recio-Blanco, T. Tepper-Garcia +7

Among the various implications of the spiral arms, it has been observed in the Milky Way disc that the distribution of radial actions from the Gaia Data Release 3 exhibits structur…
